2. Description of the Related Art Conventionally, so-called endorsement is generally performed on the back surface of securities such as checks, bills and securities.

This endorsement is made to prove the validity of securities and to prove that the securities have been received.

In recent years, the endorsement has been performed by a recording device such as a printer. However, since endorsement is legally binding, the information on the front side and the information on the back side on which the endorsement is performed are reliable. Must correspond to.

From such a point of view, in the recording device for endorsement, once the securities have been taken into the main body, the processing is performed without touching the operator's hand until the processing is completed. At the same time, information on the front surface and information on the back surface are read and recorded.

Therefore, the endorsement recording device has a built-in information reading device such as a scanner, and is provided with a reversing mechanism for reversing securities inside the main body in order to perform front and back processing.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention As described above,
In the conventional recording apparatus 100, the information on the front surface is recorded, the securities are reversed, the endorsement recording position is detected, the endorsement is recorded, and the endorsement is performed without the operator touching the securities once inserted. In order to perform a series of processes of recording information of a recording portion, the conveyance path switching member 13 which is a medium reversing mechanism.
It is necessary to provide 0, the fifth conveyance roller 131, the sixth conveyance roller 132, and the reversal conveyance path 133.

However, according to the above construction, the medium reversing mechanism becomes large, and the recording apparatus becomes expensive and large in size.

In addition, the reversing transport path 133 has one medium.
Since it has to be rotated by 80 [°], there is a problem that the degree of bending becomes large and a medium made of a hard material cannot be handled. Further, there is a problem that the medium is easily jammed (paper jam), the reliability is low, and the securities that are the medium are damaged. Furthermore, after reading the information on both sides, the securities as the medium are inverted, that is, the back side is discharged with the front side facing the operator, which gives the operator a feeling of strangeness.

In order to solve these problems, a front surface reading mechanism having a reading sensor for reading information on the front surface of the medium and a back surface reading mechanism having a reading sensor for reading information on the back surface of the medium are provided. However, there is a problem in that the apparatus becomes expensive and the size of the apparatus increases due to systematic provision of the optical system.

It is also conceivable that one reading mechanism is mechanically rotated to sequentially switch and read from the front side and the back side of the medium, but the size of the reading mechanism is set to be equal to or smaller than the minimum length of the medium to be read. Therefore, it is necessary to make the reading sensor compact, and in reality it is necessary to use a contact sensor. However, the contact-type sensor has a shallow depth of field, and in a recording device that handles a booklet-shaped medium such as a passbook as well as securities, it cannot cope with a change in thickness such as a stitch portion. There is a problem that it cannot be adopted. Furthermore, the structure cannot be arranged inside the rotation locus of the reading sensor, which causes a problem that the recording apparatus is eventually increased in size.

Therefore, an object of the present invention is to provide an information reading apparatus and a recording apparatus which are inexpensive, highly reliable, and can be miniaturized by reducing the number of parts and moving parts. It is in.

Further, according to the present embodiment, since the reading sensor is provided in only one system for reading both the front surface and the back surface of the medium, it is possible to construct a recording apparatus equipped with an inexpensive reading device. Further, it is possible to reduce the size of the recording device.

Furthermore, since a reduction optical system can be adopted, the depth of field can be deepened, and not only sheet-like media such as checks, but also booklet-like media such as passbooks can be processed. Since it is possible, it is not necessary to provide a recording device according to the medium, and it is possible to reduce the user's system construction cost and installation location.

Furthermore, since the medium transport path does not need to be curved, a medium made of a hard material can be easily handled. Further, it is possible to reduce the possibility of causing a medium jam (paper jam), and it is possible to improve the reliability of the recording device including the reading device.

In switching the optical path, the optical system parts such as the mirror are not moved. Therefore, the optical axis shift due to the vibration at the time of driving the optical system parts and the optical shift due to the position shift after the optical system parts are driven. No axis deviation will occur.

In the above description, the half mirror having substantially the same reflectance and transmittance is used as the light guide member 37, but the present invention is not limited to this.

More specifically, the light guide member 36 (light guide section).
And the transmittance of (100-α)
When [%] is set, the irradiation light amount of the first light source 31 (irradiation unit) that irradiates the reading light L1 (first reading light) reflected by the light guide member 36 is set to A, and the reading light L2 (the other reading). light)
When the amount of light emitted from the second light source 32 (irradiation unit) for irradiating light is B and the amount of light received by the reading sensor 44 (information reading unit) when the loss due to the condenser lens 43 is ignored is C, A≈C X (100 / α) × k B≈C × {100 / (100−α)} × k (k: constant), the first light source 31 or the second light source 3
In both cases, the amount of light received by the reading sensor 44 (information reading section) can be kept constant (= C).

That is, the case where the light guide member 36 (light guide portion) of this embodiment is set to α≈50.

Further, in the above description, a series of processes of storing information on the surface of the medium, detecting the endorsement recording position, recording endorsement, and storing information on the endorsement recording portion is performed on the medium.
Although it was carried out by reciprocating, if endorsement recording position is not required to be detected and the recording position is predetermined, endorsement recording and storage of information of endorsement recording part are stored in the recording device. It is possible to carry out one reciprocation of the medium by carrying out during the transportation of the medium and storing the information on the surface of the medium during the transportation when discharging the medium.

Further, in the above description, the case of the dot impact printer as the recording apparatus has been described as an example, but the same can be applied to any printer in which the recording head is driven together with the carriage. For example, it can be applied to an inkjet printer, a thermal printer, and the like.

Furthermore, in the above description, the controller 40 controls the recording device or the medium alignment device.

As a control method of the controller 40, the control program is stored in a ROM or the like in advance, or the control program is recorded in an external recording device such as a hard disk and activated, or the control program is controlled. Can be recorded on a removable recording medium such as an optical disk for installation, or can be configured to be downloaded and installed via a network. When downloading, it is possible to download each time it is executed. Further, a computer-readable recording medium such as a ROM can be configured to be replaceable.
