DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the above-described printing position indicating apparatus for a printing machine according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a side view illustrating the internal structure of a time stamp embodying the present invention. The time stamp indicated by reference numeral 1 is generally an upper case body 1A and a lower case body 1.
B, and a main frame 2 that moves up and down around a mounting shaft 3 provided at a rear portion inside the upper case body 1A.
The main frame 2 is provided with a support frame 2a provided with a mounting plate 2b for mounting components such as a display and a switch panel (both not shown) at the end thereof. The mechanism moves up and down integrally with the main frame 2.

M, 4 and 5 correspond to the main frame 2
And the first and second interlocking gears,
When the touch plate 9 provided on the slide plate 1G of the lower case body 1B is pressed, the motor M is started and the pinion M of the motor M is started.
a, the first interlocking gear 4 meshed with the first interlocking gear 4 rotates interlockingly, the second interlocking gear 5 meshing with the pinion 4a of the first interlocking gear 4 rotates interlockingly, and the rotating shaft 5a of the second interlocking gear 5 rotates. An eccentric cam 5T attached to the eccentric cam 5T is configured to rotate in an interlocking manner, and a bearing 6 on the lower case body 1B side that presses the peripheral surface of the eccentric cam 5T, and a spring 7 that constantly pulls the main frame 2 downward. Thus, every time the eccentric cam 5T rotates, the vertical movement (contact / separation operation) is repeated with respect to the slide plate 1G of the lower case body 1B with the main frame 2 as the fulcrum of the mounting shaft 3.

In FIG. 1, reference numeral 8 denotes a printer mounted on a guide shaft 8a which is mounted on the support frame 2a.
When the main frame 2 rotates down the support frame 2a by the rotation of the printing paper C, the printing paper C inserted along the slide plate 1G
The mechanism is such that the head of the printer 8 is brought close to the printing surface of K (see FIG. 5), and the date, time, number or the like as shown in FIGS. 6 and 7 is printed on the printing surface. In some cases, instead of the printer 8, printing on the printing paper CK is performed in printing using a printing block using a printing wheel and a printing hammer or roller, and the selection is arbitrary.

In FIGS. 2 to 4, reference numerals 11 and 12 denote a mounting base 11d having a substantially semi-cylindrical cross section and mounting holes 11e, 11e provided on the right and left sides of a rear portion, respectively. , 11d are a prism lens (cylindrical lens) for designating a printing position and for a guide line, wherein 11a and 11b are a light entrance surface and a light exit surface formed on the upper and lower surfaces of the lens body 11L, and 11c is a reflection lens. Surface
As shown in FIG. 1, the prism lens 11 for designating the printing position is mounted on the back surface of the mounting plate 2b by using the mounting bases 11d and 11d in a state where it is directed sideways at right angles to the insertion direction of the printing paper CK. The guideline prism lens 12 is attached to the leading end 2c of the main frame 2 along the insertion direction of the printing paper CK by using the mounting bases 11d and 11d.
1 and 12 condense a light beam emitted from a light source mounted on the upper back surface of the mounting plate 2b, that is, a light beam emitted from an LED 10 for a pilot lamp, and as shown in FIG.
The printing position is marked with an optical mark E for specifying the printing position having the same length as the printing width, and an optical mark R for guiding the insertion of the printing paper CK.

FIGS. 3 and 4 show prism lenses 11 and 12 for condensing a light beam emitted from an LED 10 as a light source and irradiating the light beam as an optical mark E or R on the surface of a slide plate 1G.
Is a configuration diagram for explaining the function of (1), wherein the angles A ° and B ° of the incoming and outgoing light of the lens body 11L are configured to be the same angle, and in the case of the prism lens 11 for indicating the printing position, the sliding plate 1G 5, a light mark E having a height S corresponding to the printing length and a horizontal width H corresponding to the length of the printing width is attached to the sliding plate 1G as shown in FIG. In the case of the guideline prism lens 12, the guideline prism lens 12 is mounted at the same position as the focal length T with respect to the slide plate 1 G, so that the elongated guideline optical mark R having the length H is similarly formed as shown in FIG. As shown in FIG. 5, the surface of the slide plate 1G is irradiated with light.

The reason why the guideline prism lens 12 is mounted below the print position indicating prism lens 11 in FIG. 1 is to use a small prism lens having a short focal length for the guideline. If the same lens having the same focal length T is used as each of the prism lenses 11 and 12, the guideline prism lens 12 is adjusted to the focal length T to indicate the print position. Needless to say, it is used by being mounted slightly above the prism lens 11. The reason why the prism lenses 11 and 12 as shown are used as the lenses is to utilize the refraction of light, avoiding a printing portion such as the printer 18 on the line connecting the LED 10 and the slide plate 1G.

FIGS. 6 and 7 show the size and type of the light mark E applied to the surface of the sliding plate 1G. In the figures, Ea denotes a standard size light indicating the print position of the date and time. Eb is a slightly larger size light mark indicating the print position obtained by adding a number to the date and time, and Ec is a special size light mark indicating the print position of the die plate, and is a slightly larger size light mark. Eb can be radiated by moving the mounting position of the prism lens 11 slightly below the standard size Ea to widen the printing width H shown in FIG. 4, and the special size optical mark Ec is a special prism. Illumination can be achieved by using a lens (not shown).

In FIG. 8, reference numeral 20 denotes a concave mirror capable of irradiating the upper surface of the sliding plate 1G with the optical marks E and R for indicating the printing position and for the guide line instead of the prism lenses 11 and 12 described above. Thus, this concave mirror 20, which is formed to be horizontally long and the reflecting surface 20a is formed to be concave,
By mounting the time stamp 1 downward on the mounting plate 2b, the light beam emitted from the LED 10 is reflected and condensed to irradiate the surface of the sliding plate 1G with the optical mark E for indicating the printing position, or By changing the mounting angle and mounting position of the concave mirror 20, it is possible to irradiate the guide sheet R for the printing paper CK on the surface of the slide plate 1G.

Since the printing position indicating device for a printing machine according to the present invention has the above-described configuration, it is used as a time stamp 1 or a time recorder (not shown) as shown in FIG.
The guide mark R and the light mark E for indicating the printing position condensed by the prism lenses 11 and 12 or the concave mirror 20 are located at the printing position and the guide line position of the slide plate 1G for guiding the insertion of the printing paper CK. Can be irradiated respectively, the stamper first inserts the printing paper CK correctly along the optical mark R for the guideline,
Next, the printing of the time or the like can be performed while visually checking the position of the optical mark E for indicating the printing position, and the change of the printing width H can be performed by moving the mounting position of the prism lens 11 or the concave mirror 20. By adjusting the distance from the sliding plate 1G, the length can be freely changed in accordance with the contents of printing.

[0025]

As described above, according to the printing position indicating apparatus for a printing machine according to the present invention, an optical mark indicating a printing position and a guide line can be applied to the surface of the slide plate of the printing machine. The user can insert the printing paper according to these optical marks and print the date and time correctly at the designated position, and use no plastic plate or film for indicating the printing position. Can solve the problem of, can provide a printing machine with a high-quality image using light and clean, using a pilot lamp of the printing machine as a light source can be made as cost-effective as a mechanical type, and Combined with the fact that it is possible to easily print with different character widths simply by moving the mounting position of the prism lens or concave mirror without replacing parts,
