Card holding structure for portable electronic device
View Patent ↗In a portable electronic device, a card holding structure includes a plurality of holding members formed on a case to hold a card on a card connector having no holding member. The holding members include a flexible arm with an engaging portion and a stationary portion. The card can be attached/detached to/from the portable electronic device by bending the flexible arm.
1. A card holding structure for use in a portable electronic device including a case and a card connector, comprising: a plurality of holding members formed on the case to hold a card down on the card connector,
wherein the card connector has contact terminals to be electrically connected to contact portions of the card; and
wherein said holding members include a flexible arm, said flexible arm being attached to said card holding structure at only one end, and being bent when the card is attached/detached to/from the portable electronic device, a main stationary portion, and a non-flexible subsidiary stationary portion projecting within the case and in parallel with the main stationary portion, to cooperate with said main stationary portion, said subsidiary stationary portion and said main stationary portion simultaneously contacting opposite surfaces of the card when supporting the card.
2. A card holding structure claimed in claim 1 , wherein said holding members hold the card by means of resilience of the card connector.
3. A card holding structure claimed in claim 2 , wherein the resilience acts in a thickness direction of the card.
4. A card holding structure claimed in claim 1 , wherein said flexible arm is made of elastic material.
5. A card holding structure claimed in claim 1 , wherein said flexible arm is coupled to the case with a rotation axis.
6. A card holding structure claimed in claim 1 , wherein said flexible arm comprises an arm body and an engaging portion protruding from said arm body to hold the card down.
7. A card holding structure claimed in claim 1 , wherein said the card comprises a subscriber identification module card.
8. A portable electronic device including a case, a card connector and a card holding structure, wherein the card holding structure comprises: a plurality of holding members formed on the case to hold a card down on the card connector,
wherein the card connector has contact terminals to be electrically connected to contact portions of the card; and
wherein said holding members include a flexible arm, said flexible arm being attached to said card holding structure at only one end, and being bent when the card is attached/detached to/from the portable electronic device, a main stationary portion, and a non-flexible subsidiary stationary portion projecting within the case to and in parallel with the main stationary portion, cooperate with said main stationary portion, said subsidiary stationary portion and said main stationary portion simultaneously contacting opposite surfaces of the card when supporting the card.
9. A portable electronic device claimed in claim 8 , wherein said holding members hold the card by means of resilience of the card connector.
10. A portable electronic device claimed in claim 9 , wherein the resilience acts in a thickness direction of the card.
11. A portable electronic device claimed in claim 8 , wherein said flexible arm is made of elastic material.
12. A portable electronic device claimed in claim 8 , wherein said flexible arm is coupled to the case with a rotation axis.
13. A portable electronic device claimed in claim 8 , wherein said flexible arm has an arm body and an engaging portion protruding from said arm body to hold the card down.
14. A portable electronic device claimed in claim 8 , wherein said the card comprises a subscriber identification module card.
15. A card holding method for holding a card in a portable electronic device including a case and a card connector, the card connector having contact terminals to be electrically connected to contact portions of the card, the method comprising the steps of: inserting an edge of a card between a main stationary portion and a subsidiary stationary portion each formed on the case; turning the card by using the edge of the card as an axis; and engaging an engaging portion provided on a flexible portion formed on the case with another edge of the card by bending and returning the flexible portion to press the card on the card connector down, the subsidiary stationary portion comprising one or more non-flexible projections within the case and in parallel with the main stationary portion, that cooperate with the main stationary portion, the subsidiary stationary portion and the main stationary portion simultaneously contacting opposite surfaces of the card when supporting the card.
