Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a portable / rear-end knock-type writing instrument in which a knock body at the rear end of a shaft cylinder is moved back and forth to retract a cartridge.

(Prior Art) It has long been considered to add not only a writing function but also other functions to a portable writing instrument by taking advantage of the convenience and convenience of carrying. For example, magnifying lens, earpick,
Knives, clocks, rulers, etc.

Step counting is one of them. For example, Japanese Utility Model Laid-Open No. 57-8512 discloses that the name of the device is “portable pedometer”, but according to the specification attached to the application, , There is a statement that a cursive body is accommodated in the lower part of this portable pedometer.

(Problems to be solved by the device) It is better to prevent erroneous operations as a result of the step counting function being exerted while the writing function is exerting. That is, if it is according to the above-mentioned publication, if the pedometer is continuously used during writing as a writing instrument to measure the number of steps, it is thought that, for example, it will be necessary to take 10,000 steps a day to eliminate lack of exercise. It will be useless for those who are.

(Means for Solving the Problem) There are various types of portable writing instruments as well. In the present invention,
A rear-end knock type in which the knock body at the rear end of the barrel is moved back and forth to allow the cartridge to be retracted and used is used. The knocking operation of the knocking body is also used as the stopping operation of the step counting function.

That is, the present invention is a portable / rear-end knock-type writing instrument in which a knock body at the rear end of a shaft cylinder is moved back and forth so as to retract a cartridge, and displays a step count measurement operation unit and a step count measurement value. A step count measuring mechanism consisting of a display unit and a conversion switch for stopping / continuing the step count measurement is provided, where the step count measurement is stopped when the knock body moves forward, and the step count measurement is continued when the knock body moves backward, The gist is a writing instrument including a knock body and the conversion switch as an interlocking body.

(Example) An example will be described with reference to the accompanying drawings. In FIG.
The cartridge 2 housed in the barrel 1 has a spring 3
Is urged rearward by the knock body 4 to the locking portion 4a.
At this point, the cartridge 2 is engaged with the shaft cylinder 1 to prevent the cartridge 2 from falling off the shaft cylinder 1. Here, knock body 4
Has a projecting pin 6 urged by a spring 5 at its front end portion. The projecting pin 6 projects from a through hole 1a formed in the barrel 1 and abuts the back surface of the clip 7. . In this example, the clip 7 serves as a step count measuring unit, which will be described later.

FIG. 2 shows a state in which the knock point 4 is pressed and the pen tip portion 2a of the cartridge 2 is projected from the barrel 1. At this time,
The protruding end 6 a of the protruding pin 6 is located in the internal space formed in the clip 7 after passing through the through hole 7 a formed in the back surface of the clip 7 for a predetermined length. By the protrusion of the protrusion pin 6,
The pen tip portion 2a is kept protruding from the barrel 1 for writing.

FIG. 3 is a front view of the clip 7 (upper side in FIGS. 1 and 2), in which a liquid crystal display portion 8 and a reset portion 9 are formed.

FIG. 4 shows its internal structure, in which a button battery 10 as a power source, a pendulum 12 suspended by a spring 11, and a terminal 13 are arranged. Where the pendulum 12 is
The left end of the drawing is a fulcrum, and the right end is a pyramidal part. When standing upright in FIG. 4, the right end of the swaying pendulum 12 comes into contact with the terminal 13, and the number of times is displayed on the liquid crystal display unit 8. Displayed as steps. Reference numeral 14 is a stopper for restricting the swing of the pendulum 12.

The protruding end 6a of the protruding pin 6 passes through the through hole 7a on the rear surface of the clip 7 and is positioned in the internal space of the clip 7 just at the portion that blocks the contact between the pendulum 12 and the terminal 13. This effect of the protruding pin 6 is shown in FIG.

When you want to return the pen tip 2a to the inside of the barrel 1 after you finish writing, for example, press the rear part of the clip 7 (the right part of the drawing) (from the upper part of the drawing) to raise the clip 7 to the left of the drawing. The protruding pin 6 is pulled out, and the cartridge 2 is displaced rearward by the elastic force of the spring 3. When carrying, the number of measurements continues again, and of course, if you want to start from scratch again, you can reset it.

As described above, in this example, the pendulum 12 serves as a step count measuring operation unit, and the step count measurement value is displayed on the display unit via the counting circuit using the opening and closing of the electric circuit by the pendulum 12. Also, the projecting pin 6 which is linked with the knock body 4 serves as a stop / continue exchange switch for measuring the number of steps, but various other modifications are possible. For example, instead of the protruding pin 6 that blocks the contact between the pendulum 12 and the terminal 13,
When it is not desired to measure, an ON-OFF power supply for cutting off the electric circuit may be provided, and the switch of this power supply may be a conversion switch that works in conjunction with knock body 4. Further, for example, in the above-mentioned one, the step count measuring unit is the clip unit in consideration of the fact that the measured number is always known when viewed, but the step count measuring unit may not necessarily be the clip unit. Some people may not want others to realize that they carry a pedometer. Further, for example, the type of writing instrument may be a fountain pen, a mechanical pencil, a ballpoint pen, or the like.

(Effect of device) The step count may be taken only while walking. I would like to avoid the writing movement from adding to the number of measurements. In the writing instrument of the present invention, since the knocking operation as the writing instrument also serves as the stop operation of the step counting function, in order to satisfy this, it can be performed unconsciously and naturally.
In addition, checking the position of the knocking body when carrying the device in order to measure the number of steps also prevents the carrying of the cartridge in the protruding state.
