2. Description of the Related Art Conventionally, an ophthalmologic apparatus such as a visual acuity test apparatus having a printing function is known. These ophthalmologic apparatuses include a printer unit 10 inside the ophthalmic apparatus as shown in FIG. The printer unit 10 includes a roll paper 11 on which a recording paper 11a is spread, a printing unit 20, and a cutter blade 12 for cutting the recording paper 11a. The printing unit 20 includes a guide member 21 that guides the recording paper 11a to the printing unit 13;
The recording head includes a head section 22 for printing on a, and a roller section 23 for sending out recording paper.

In such a printer unit 10, a printing unit 20 is used.
Paper 11 stretched from roll paper 11 using
Then, printing is performed on the recording paper 10a, and a predetermined amount of the recording paper 10a is discharged from the discharge port 13. Thereafter, the recording paper 11a is manually pulled and pressed against the cutter blade 12 provided in the discharge port 13, thereby cutting the recording paper 11a.

[0004]

However, in the case where an unspecified number of subjects use the conventional ophthalmic apparatus and cut the recording paper 11a discharged from the discharge port 13 by themselves, the cutter blade 12 is not used because it is inexperienced. It may be pulled without pushing it. Since the recording paper 11a pulled without being pushed up by the cutter blade 12 is torn off and biased, the paper cannot be cut cleanly at the discharge port 13 and paper jams often occur.

The present invention has been made in view of the above-mentioned problems of the prior art,
It is an object of the present invention to provide a printer which is less likely to cause a paper jam no matter how the recording paper is cut, and an ophthalmologic apparatus having the printer.

After pressing the start button 5, the subject looks inside the examination window. When the start button 5 is pressed,
The control unit 44 turns on the illumination lamp 42R (L) and presents the test target formed on the target disk plate 41 to the subject according to the test program stored in the memory 46. The procedure of the examination is transmitted from the voice guide generator 45 to the subject through the speaker 6. The subject performs an eyesight test using the joystick 3 and the response button 4 while listening to the voice guide.

When one kind of inspection is completed, the control unit 44 prints the inspection result on the recording paper 11a by the printer unit 10 and discharges the printed result. Recording paper 11 on which inspection results are printed
a is the recording sheet 1 discharged from the guide member 31 by the subject.
Take 1a and cut it out.

FIG. 5 is a diagram showing a state when the recording paper 11a is cut.

As shown in FIG. 5A, when the recording paper 11a picked up is pulled upward while being lifted (in the direction of the arrow), the recording paper 11a is pressed against the cutting edge of the cutter blade 12. For this reason, even if the recording paper 11a is pulled upward or forward (in the direction of the operation unit in FIG. 2), the recording paper 11a is easily cut without being broken in the middle, and the cut end is in a clean state.

Further, as shown in FIG. 5B, when the picked-up recording paper 11a is pulled downward (in the direction of the arrow), the leading end 31a of the guide member 31 is located above the cutting edge. , The recording sheet 1 with the tip portion 31a as a fulcrum
1a is pressed against the cutting edge of the cutter blade 31. For this reason, the recording paper 11 is moved downward or forward as it is.
The tension to the cutter blade 12 can be maintained even when the pulling a is performed, and the cutter blade 12 is easily cut without being broken on the way.
The cut is also beautiful.

As described above, the discharged recording paper 11a is pressed against the cutter blade 12 at an acute angle no matter which direction it is pulled, and is cut cleanly. Paper jams caused by misalignment (bias) can be suppressed.

In the above embodiment, the guide member 31 guides the discharged recording paper 11a upward. However, the present invention is not limited to this, and the guide member 31 guides the guide sheet 31 with respect to the cutting edge direction of the cutter blade 12. The direction (paper discharge direction) may be reversed, and the configuration may be such that when the recording paper 11a is pulled in the blade edge direction, the leading end portion 31a becomes a fulcrum when cutting and the blade edge becomes an action point. For example, the configuration of FIG. 3 may be reversed.

As shown in FIG. 6, it is also possible to use a guide member 31 'which is large enough to allow a finger to enter a receptacle (opening) of the recording paper 11a. In this case, after the recording paper 11a is discharged from the discharge port 13, the recording paper 11a can be easily taken out without being rounded and coming out of the opening. The problem of getting up is eliminated. In addition, bottom 3
By making 1'b wider, it can also be used as a saucer.

Further, in the present embodiment, the visual acuity test apparatus operated by the subject himself and outputting the test result is used. However, the present invention is not limited to this. The present invention can also be applied to an ophthalmologic apparatus such as a lens meter that measures the power of a device or a lens and outputs the result.

[0037]

As described above, according to the present invention, the guide member is provided at the discharge port so that the recording paper discharged to the outside of the apparatus can be pressed against the cutter blade regardless of the direction in which the recording paper is pulled. As a result, the recording paper can be cut cleanly, and paper jam near the discharge port can be suppressed.
