Sheet handling machine
View Patent ↗An automated handling machine for bills and securities which automatically processes bills and securities such as checks in the same apparatus. Sheets set in a bill depositing/dispensing mechanism are conveyed at a bill reading speed v 1 in a first processing mode, and when they are passed through a discriminator for bills and checks, each sheet is discriminated whether it is a bill or check. If the sheet is a bill, it is subjected to authentication discrimination, denomination discrimination and validity discrimination, and temporarily stored in a temporary stocker. If the sheet is a check, it is temporarily returned to a deposit/withdrawal port and temporarily stored there. Then in a second processing mode, the temporarily stored check is conveyed to the discriminator at a check reading speed v 2 (v 2 <v 1 ). MICR characters described on the check are read with high accuracy with a magnetic sensor of the discriminator, and contents of description on the check are obtained as image data by an image sensor, and recognition is performed on the data.
1. A sheet handling machine comprising:
a receiving port to receive sheets from a user;
a conveyor to convey sheets including bills and securities;
a discriminator to identify the sheets conveyed by the conveyor;
a holder included in the receiving port for temporarily holding sheets determined by the discriminator to be securities; and
a mechanism controller coupled to control the conveyor;
wherein the mechanism controller controls the conveyor to convey the sheets placed at the receiving port to the discriminator at a first speed, and controls the conveyor to convey the securities held in the holder to the discriminator at a second speed slower than the first speed.
2. The sheet handling machine according to claim 1 further comprising a returning port to return the sheets to the user, and wherein the holder is included in the returning port.
3. The sheet handling machine according to claim 1 further comprising plural storing boxes to separately store the bills and securities identified by the discriminator.
4. The sheet handling machine according to claim 1 wherein if a sheet is determined to be a bill, the conveyor conveys the bill to a temporary stacker.
5. The sheet handling machine according to claim 1 wherein the discriminator includes a magnetic sensor and an image sensor, and the discriminator reads MICR characters on the security with the magnetic sensor, obtains an image of the security with the image sensor, and performs character recognition based on the image.
6. The sheet handling machine according to claim 1 wherein the discriminator operates in a first discrimination mode to determine if a sheet is a security, and in a second discrimination mode to determine at least some content of the security.
7. The sheet handling machine according to claim 6 wherein the discriminator further includes a bill discrimination mode for obtaining denomination information of sheets determined to be bills.
8. The sheet handling machine according to claim 1 wherein the conveyor conveys a sheet determined to be an unauthorized security to the receiving port.
