In the figure, reference numeral 106 denotes a parallel interface as an input interface for receiving print data from an external portable information processing device. The print data received via the parallel interface 106 is stored in a RAM 107 provided inside the paper feeder.

According to this configuration, the infrared communication module and the like become unnecessary, and the housing of the printing member can be made small. Furthermore, since print data is transmitted and received to and from the external portable information processing device via a wire, data can be reliably transmitted and received even when infrared communication is difficult due to disturbance light or the like. Further, in the present embodiment, an example in which a parallel interface is used as an input interface has been described.

The LED driver 260 controls light emission of the LED 259. The light reflected on the recording medium is photoelectrically converted by the CCD 261 and further converted to a digital signal by the A / D converter 262.

The operation of the portable reader constructed as described above will be described.

As described above, the reading by the reading member 203 may be performed manually by holding only the read recording medium transport device 203 alone, or may be performed mechanically by mounting it on the carriage 4. .

In the case where the scanning is performed independently, the operator holds the reading / recording medium transport device 203 by hand, and
4 is pressed against a reading sheet to be read, and is swept in the reading direction. Then, the LED 259 emits light and irradiates the reading sheet. The CPU 271 knows the rotation by generating a position signal from the encoder 255, and synchronizes with the position signal based on the digital signal from the A / D converter 262 to synchronize with the position signal.
The read data is stored in the AM 273.

Thereafter, the read data is transferred to an external portable information processing device (not shown) by the infrared light communication module 258.

When reading is performed with the reading member 203 mounted on the carriage 4, the operator mounts the reading member 203 on the carriage 4, and further, the operator loads the read sheet to be read from the sheet supply port 6b. Insert in the direction of the discharge port 6c and set.

Thereafter, when the reading start switch provided on the operation key section 9 is pressed, the control circuit provided on the substrate 42 drives the pulse motor 16 and the carriage 4 moves. Reading is performed by the reading unit 253 in the reading member 203, and the reading operation is continued until reading of one line is completed.

When reading of one line is completed, the pulse motor 16 is rotated in the reverse direction to return the carriage 4 to the home position, and the pulse motor 25 as a transport motor is driven to rotate the transport roller 21 by a predetermined amount. Then, the reading paper is fed by a specified amount and the next line is read.

The operator transfers the read data to an external portable information processing device (not shown) by infrared communication using the infrared light communication module 258.

According to the above configuration, reading can be performed by the reading member alone including the reading head, the reading medium is not limited by the limitation of the length of the cable, and only a smaller reading member can be carried. Is possible.

As an example different from the above-described embodiment, a paper feeder may be provided with an output interface for outputting read data to an external portable information processing device.

According to this configuration, the infrared communication module and the like become unnecessary, and the reading member housing can be made small. Further, since the transmission and reception of the read data to and from the external portable information processing apparatus are performed by wire, the data can be reliably transmitted and received even when the infrared communication is difficult due to the influence of disturbance light or the like. Further, in the present embodiment, an example in which a parallel interface is used as an input interface has been described. However, similar effects can be obtained by using an external interface provided in an external portable information processing device such as a serial interface or a PCMCIA interface.

The power may be supplied to the reading member 203 from the battery in the paper feeder 1 having a large capacity. Alternatively, the paper feeder 1 may be configured to use a commercial AC power supply and charge the secondary battery of the reading member 203. The point is that any configuration is possible as long as the reading member can supply power required for reading from the paper feeding device. According to this configuration, since the reading member only needs to store the minimum power required for reading, the reading member housing can be configured to be small.

When the reading member is provided with a position detecting means such as an encoder 255, the reading member is mounted on the paper feeding device in addition to detecting the relative movement amount with respect to the recording medium when the reading member is used alone. It can be configured to detect the amount of relative movement with respect to the recording medium when the device is used. In this case, the mechanism of the paper feed mechanism can be simplified.

Further, even when the above-mentioned printing member and reading member are integrated, the above-mentioned method of use is of course possible.
