an operating device to be operated by the user; and
a control device controlling said display device; wherein
said display device and said operating device are arranged close to each other; and
control device includes:
a transition control unit controlling said display device such that said standby image is displayed if a predetermined transition condition related to a state of said information equipment is satisfied,
a return control unit controlling said display device such that said operation is displayed if a predetermined return condition related to a user operation using said information equipment is satisfied, and
a switch control unit controlling said display device such that, when a request for displaying said operation image is issued from said return control unit while said standby image is being displayed and transition is made from said standby image to said operation image in response to said request, a specific image including a piece of information different from said operation image and said standby image is displayed after ending display of said standby image and before starting display of said operation image, when said standby image is switched to said operation image.
2. The information equipment according to claim 1 , wherein said switch control unit includes a first control unit controlling said display device such that said specific image is displayed for a time period of a predetermined length.
3. The information equipment according to claim 2 , wherein said switch control unit further includes a second control unit controlling said display device such that said operation image is displayed if the user operates said operating device in the time period in which said specific image is displayed.
4. The information equipment according to claim 1 , wherein said specific image includes a piece of information related to information included in said standby image.
5. The information equipment according to claim 1 , wherein said specific image includes a piece of information related to the user using said information equipment.
6. The information equipment according to claim 1 , wherein said transition control unit includes a transition unit controlling said display device such that said standby image is displayed if a condition that the user does not operate said operating device for a time period of a predetermined length is satisfied.
7. The information equipment according to claim 1 , wherein said return control unit includes a return unit controlling said display device such that said operation image is displayed if a condition that the user operated said operating device is satisfied.
8. The information equipment according to claim 1 , wherein said standby image is a screen saver image.
9. The information equipment according to claim 1 , wherein said display device includes a pressure-sensitive selection button for realizing a function of said operating device.
10. The information equipment according to claim 1 , further comprising:
a communication device for communication with external equipment; and
a receiving device receiving either a piece of information for displaying said standby image or a piece of information for displaying said specific image, from said external equipment.
11. An image forming apparatus, comprising:
the information equipment according to claim 1 ; and
an image forming unit forming an image on a sheet of recording paper.
12. The image forming apparatus according to claim 11 , further comprising a display control unit controlling said display device such that said specific image is displayed during image formation on recording paper by said image forming unit.
13. In information equipment switching display of an operation image and a standby image, including a display device displaying information to a user and an operating device to be operated by the user arranged close to said display device, a method of display comprising the steps of:
controlling said display device such that said standby image is displayed if a predetermined transition condition related to a state of said information equipment is satisfied;
controlling said display device such that said operation image is displayed if a predetermined return condition related to a user operation using said information equipment is satisfied; and
controlling said display device such that, when a request for displaying said operation image is issued while said standby image is being displayed and transition is made from said standby image to said operation image in response to said request, a specific image including a piece of information different from said operation image and said standby image is displayed after ending display of said standby image and before starting display of said operation image, when said standby image is switched to said operation image.
