Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a line indicator for a document held between paper clips on a stand when printing characters using, for example, a word processor.

(Conventional technology and problems) A conventional line indicator of this kind is shown in FIG.

That is, the row indicator B consists of a slider body 20 made of synthetic resin into which a row indicator piece 21 is integrally molded, and a cover 22 made of synthetic resin attached to the slider body 20.

Therefore, the slider body 20 has a pressing body 23.
, a coil spring 24 attached to the back surface of the pressing body 23 , and a pair of guide walls 25 formed on the slider body 20 to which the other end of the coil spring 24 is attached.
An adjustment plate 26 that slides along the adjustment plate 26 and a screw rod 28 having a knob 27 that comes into contact with the back surface of the adjustment plate 26 and is screwed into the slider main body 20 are installed inside.
The pressing body 23 is provided with a pair of protruding walls 30 that straddle a pair of stopper walls 29 provided on the slider body 20, and normally the coil spring 2
4, it is in contact with the stopper wall 29 due to the pressing force.

Further, the pressing body 23 is provided on the back surface of the cover 22.
A clamping body 31 is provided that cooperates with the L-shaped side wall of the viewing platform to sandwich the side wall thereof.

As described above, the conventional row indicator B adjusts the pressing force of the pressing body 23 by the coil spring 24 with the knob 27, is held on the side wall of the viewing platform with an appropriate pressing force, and the row indicator piece 21 is moved. Although it is possible,
There are the following problems.

(a) It is desirable that the row indicator has a large sliding resistance when sliding downward to ensure the transition of the row indicator piece to the next row, and a small sliding resistance when sliding upward. , since the conventional row indicator B is pressed by a coil spring 24,
The sliding resistance is the same when sliding in the vertical direction, and the above requirements are not met.

(b) The base end of the row indicator piece 21 is the slider body 20
Since it is integrally formed with height h,
The number of original sheets is limited by the height h, which causes inconvenience in use.

(Means for Solving the Problems) The present invention provides a line indicator that solves the above problems, and is composed of a slider body,
It consists of a cover attached to the slider body and a row indicator piece detachably attached to the cover, and the slider body has a pair of upper and lower sliding parts facing each other that slide on the inner and outer surfaces of the side wall of the viewing platform. At the same time, a vertically elongated sliding portion that slides on the back surface of the viewing platform is formed, and the lower end of the curved portion is approximately D-shaped and has an adjustment screw that adjusts the pressing force against the outer surface of the side wall of the viewing platform. The cover is provided with an insertion opening for an insertion portion formed at one end of the row indicator piece, and a plurality of engagement recesses formed in series in the insertion portion. The device is characterized in that a locking body is formed that selectively engages with the locking body.

(Example) Embodiments of the present invention will be described with reference to the drawings.

As shown in the exploded perspective view of FIG.
consists of a slider body 1, a cover 2 attached to the slider body 1, and a row indicator piece 3 detachably attached to the cover 2.

The slider main body 1 includes a pair of upper and lower sliding parts _1a1 that slide on the outer surface of the side wall of the viewing platform, and a substantially D-shaped elastic pressing body 4 that presses the outer surface of the side wall of the viewing platform. A partition wall 1 is installed on the back side of the vertical part 4a of
A gripping part _1a abuts the tip of an adjusting screw 6 having a knob 5 screwed into the gripping part 1a, and a rear wall 7 of the gripping part 1a (see FIG. 2), and namely, a pair of sliding parts 1b ₁ that slide on the inner surface of the side wall of the viewing platform facing the viewing platform 1a ₁ , and a sliding contact portion 1b that includes a vertically elongated sliding portion 1b ₂ that slides on the back surface of the viewing platform. has been done.

The substantially D-shaped elastic pressing body 4 is made of polyacetal resin (trade name: DURACON resin) with good elasticity and lubricity, and the lower end face of the curved part 4b is cut out over the entire width, and the lower end of the vertical part 4a is cut out. and facing each other with a distance between them.

Moreover, polyacetal resin is attached to the sliding parts 1b ₁ and 1b ₂ .

An insertion opening 2a for the insertion part of the row indicator piece 3 is formed at the rear of the cover 2, and a forked locking body having a slit _2b1 is inserted from the rear end of the insertion opening 2a. 2b are orthogonally protruded, and a locking protrusion _2b2 is formed at the tip of the locking body 2b.

In addition, a vertically elongated sliding part 2c attached with polyacetal resin is formed on the front back of the cover 2, and the sliding part 2c is attached with polyacetal resin, and the sliding part 2c is attached to the front side of the viewing platform. A fitting long groove 2d is formed.

A forked insertion part 3a having a slit _3a1 inserted into the insertion opening 2a of the cover 2 is formed at one other end of the row indicator piece 3, and is bent at a right angle.
A locking body 2 of the cover 2 is provided on one surface of the insertion portion 3a.
A plurality of engaging recesses 3a ₂ are formed to selectively engage with the locking protrusion 2b ₂ of b.

Therefore, as shown in FIG.
into the insertion long groove 2d of the cover 2, and insert the insertion part 3a.
When inserted into the insertion slot 2a, the locking protrusion _2b2 is engaged with the uppermost engagement recess _3a2 , and the insertion part 3
If you push a upward, the engagement recess 3a ₂ and the locking protrusion 2b ₂
The line indicator piece 3 moves upward by the articulated engagement with the line indicator 3.

To assemble the row indicator A, the slit _2b1 of the locking body 2b of the cover 2 is inserted into the adjustment screw 6 of the slider body 1, and the cover 2 is screwed onto the slider body 1.

Next, the row indicator piece 3 is fitted into the long insertion groove 2d of the cover 2, and the slit _3a1 of the insertion portion 3a protruding from the insertion opening 2a is inserted into the adjustment screw 6.

FIG. 5 shows the back side of the viewing platform 8, where a side wall 8a bent in an L-shape toward the back side is formed on the side, and a pair of protrusions 8b are formed in parallel in the vertical direction. .

FIG. 6 shows a top view of the line indicator A fitted into the side wall 8a of the platform 8, and the curved portion 4b of the elastic pressing body 4 presses the outer surface of the side wall 8a, so that the inner surface of the side wall 8a becomes a slider. At the same time as being pressed against the sliding portion 1b ₁ of the main body 1, the vertically long sliding portion 1b ₂ of the slider body 1 is pressed against the pair of protrusions 8b of the viewing platform 8, and the vertically long sliding portion 2c of the cover 2 is pressed against the viewing platform. The line indicator piece 3 is pressed against the front side of the line indicator 8 to hold the line indicator piece 3 in a predetermined position, and can be slid up and down.

Therefore, when the row indicator A slides downward, it resists the elastic force expanding outward of the curved portion 4b of the elastic pressing body 4, so the sliding resistance is large, and the upward movement When sliding to the curved part 4b
The sliding resistance becomes smaller as the elastic force is allowed to expand outward.

(effect) The present invention has the following effects.

(a) Since the distance between the line indicator and the stand changes in several steps, it is possible to accommodate a larger or smaller number of manuscripts to be placed on the stand, making it convenient to handle.

(b) Since we use a nearly D-shaped elastic press with one end open, the sliding resistance is different when the row indicator slides up and down, making it possible to ensure the downward transition and also to ensure the upward transition. can be done smoothly and quickly.
