Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus for discriminating erroneous detection of a sensor for detecting the position of a recording medium. In the financial field, a computer is introduced, and a recording device (printer) performs necessary printing processing on a passbook or a slip as a recording medium. In financial relations, the accuracy of processing is particularly required. Therefore, it is necessary to minimize the obstacle of the conveyance of the recording medium due to the erroneous detection of the sensor that detects the position of the recording medium.

[0002]

2. Description of the Related Art In a conventional recording apparatus, a passbook which is a recording medium is sucked through a suction port of a passbook section, and a slip which is a recording medium is sucked through a suction port of a slip section and is separated by a separator at a collecting section. To be The recording medium is conveyed to a printer section by a conveying roller driven by a drive motor, and printing is performed by a print head. The position of the recording medium is detected by the sensor, and the drive motor is controlled based on the output information of the sensor.

Here, as shown in FIG. 8, let us consider a case where the sensor 1 conveys the recording medium 2 from the shielding state to the transmission state. In FIG. 8A, the sensor 1 is shielded by the recording medium 2, but in FIG. 8B, the recording medium 2 is conveyed so that the sensor 1 is semi-transparent. In FIG. 8C, the recording medium 2 is completely transmitted. It becomes transparent.

The sensor 1 is operating normally, and the sensor 1
Subsequent conveyance processing is performed based on the output information of. However, even if the recording medium 2 passes through the sensor 1 as shown in FIGS. 9B and 9C, the sensor 1 is shielded against the shielding of the sensor 1 as shown in FIG. 9A. A situation may occur in which 1 remains shielded.

[0005]

In such a conventional recording apparatus, even if the recording medium actually passes through the sensor, the sensor remains shielded. If erroneous detection occurs, detection deviation from the actual position of the recording medium will occur, and subsequent conveyance will not be performed normally.

The present invention has been made in view of the above conventional problems, and an object of the present invention is to perform a normal carrying process by discriminating an erroneous detection of a sensor.

[0007]

FIG. 1 is a diagram for explaining the principle of the present invention. The present invention is directed to a recording device that controls the drive motor 19 for conveying the recording medium 13 based on the output information of the sensor 63 that detects the position of the recording medium 13, and based on the output information of the sensor 63. The discriminating means 67 for discriminating occlusion or transmission, and for conveying the recording medium 13 to a position where transmission or occlusion occurs when discriminating occlusion or transmission, and returning the recording medium 13 to the initial position when transmission or occlusion is not discriminated. The control means 69 for controlling the drive motor 19 is provided.

[0008]

According to the recording apparatus of the present invention having such a configuration, whether the sensor 63 is shielded or transmitted is determined based on the output information of the sensor 63, and the recording medium 13 is conveyed to the position where the transmission or the shield is formed. When the transmission or occlusion is not discriminated, the recording medium 13 is returned to the initial position and the occlusion or transmission is discriminated, so that the erroneous detection of the sensor 63 can be discriminated and the error processing can be performed.

As a result, it is possible to prevent the deviation from the actual position of the recording medium 13, and it is possible to carry out the normal conveyance.
