The device housing 100 has a first length in the direction of the length dimension of the writing device, a first width in the direction of the width dimension of the writing device, and a first height in the direction of the height dimension of the writing device.
The device housing 100 may comprise a first end face facing in a direction in which the first length is located, i.e. the first end face is an end face determined by a first height and a first width of the device housing 100. The first end surface includes a light-transmitting region 110, and the light-transmitting region 110 may transmit light so that the light may transmit through the first end surface.

The first light guide 230 plays a role of guiding light, and the end of the first light guide 230 connected to the light transmission region 110 has a small size in the height direction or the width direction of the writing instrument, and compared to the case where the first optical device 210 is directly connected to the light transmission region 110, the first light guide 230 can reduce the occupation of the space in the height direction and the width direction of the writing instrument, thereby making the writing instrument thinner.
The second optical device 220 includes a second working surface 221, and the second working surface 221 is configured to be optically connected to the light-transmitting region 110, so that the first optical device 210 and the second optical device 220 can be optically connected to the light-transmitting region 110 through the first working surface 211 and the second working surface 221, respectively, and thus the first optical device 210 and the second optical device 220 can perform an optical function through the light-transmitting region 110.
The writing device disclosed in the embodiment of the present application improves the structure of the writing device in the related art, the optical module 200 including the first optical device 210, the second optical device 220 and the first light guide device 230 is additionally arranged in the device housing 100 of the writing device, the first optical device 210 and the second optical device 220 are sequentially arranged in the housing inner cavity 120 along the direction of the first length, and the second optical device 220 is located between the first optical device 210 and the light transmission region 110, so that the first optical device 210 and the second optical device 220 can be prevented from being arranged in the width direction or the height direction of the device housing 100 side by side.
Moreover, the first working surface 211 of the first optical device 210 is connected to the light-transmitting area 110 through the first light guide device 230, the second working surface 221 of the second optical device 220 is connected to the light-transmitting area 110 through the light path, so that the first optical device 210 and the second optical device 220 can be respectively connected to the light path of the light-transmitting area 110 through the first working surface 211 and the second working surface 221, so that the optical module 200 can be communicated with the external light of the writing device, thereby ensuring that the writing device can realize the optical function of the writing device through the optical module, that is, the writing device disclosed in the embodiment of the present application can reduce the size of the writing device in the height direction or the width direction without affecting the normal optical function of the optical module 200, thereby making the writing device thinner.
In an alternative, as shown in fig. 1, the second optical device 220 may have a second length, a second width and a second height, the second working surface 221 extends along a direction of the second length, the direction of the second length is consistent with the direction of the first length, so that the surface of the second optical device 220 defined by the second width and the second height faces the light-transmitting region 110, and the second working surface 221 does not face the light-transmitting region 110. Based on this, the writing apparatus disclosed in the embodiment of the present application may further include a second light guide 240, the second working surface 221 is connected to the light transmissive region 110 through the second light guide 240, a second length of the second optical device 220 is greater than a second width of the second optical device 220, and a second length of the second optical device 220 is greater than a second height of the second optical device 220.
In the above case, the second optical device 220 occupies a smaller dimension in the width direction and the height direction of the writing instrument and a larger dimension in the first length direction, and this way of disposing the second optical device 220 can avoid the need for an excessive space in the width direction and the height direction of the writing instrument for the second optical device 220, thereby resulting in an increase in the dimensions in the width direction and the height direction of the writing instrument. Moreover, since the writing device further includes the second light guide 240, the second working surface 221 can be connected to the light transmission region 110 through the second light guide 240, so that the second optical device 220 can be connected to the light path of the light transmission region 110 through the second light guide 240 with a smaller size, and therefore the optical function of the optical module 200 can be ensured on the premise that the second optical device 220 does not need to increase the size of the writing device in the width direction or the height direction, which is favorable for accommodating the writing device in the electronic device, and meanwhile, the optical function of the writing device is not affected.
In this embodiment, the first light guide device 230 and the second light guide device 240 may be light guide structures such as light guide glass pillars and optical fibers, and the specific types and structures of the first light guide device 230 and the second light guide device 240 are not limited in this embodiment.
In a further technical solution, the first light guiding device 230 and/or the second light guiding device 240 may be a hollow structural member, the first light guiding device 230 and/or the second light guiding device 240 may include a first light guiding section 231, a second light guiding section 232, and a reflecting member 233, the first light guiding section 231 intersects the second light guiding section 232, and the reflecting member 233 is obliquely disposed at a junction of the first light guiding section 231 and the second light guiding section 232, wherein: the reflecting member 233 may reflect the light entering the first light guiding section 231 to the second light guiding section 232, and specifically, the second light guiding section 232 may face the first working surface 211, the second working surface 221, and the light transmitting region 110. Based on this, the second light guiding section 232 can guide the light to the first working surface 211 or the second working surface 221 or the light transmitting area 110.
In this case, the first light guide 230 and/or the second light guide 240 can perform reflection and transmission of light. In the case where the first light guiding section 231 is connected to the light transmitting region 110 and the second light guiding section 232 faces the first working surface 211 or the second working surface 221, light outside the writing instrument may enter the first light guiding section 231 through the light transmitting region 110, then the light entering the first light guiding section 231 may be reflected by the reflecting member 233 and further enter the second light guiding section 232, and finally the light may be transmitted to the first working surface 211 or the second working surface 221.
Of course, it may also be: in the case that the second light guiding section 232 is connected to the light transmitting region 110 and the first light guiding section 231 faces the first working surface 211 or the second working surface 221, light outside the writing instrument can pass through the light transmitting region 110 and then enter the second light guiding section 232, the light entering the second light guiding section 232 can be reflected to the first light guiding section 231 by reflection of the reflecting member 233, and finally the light can be transmitted to the first working surface 211 or the second working surface 221.
The first and second light guides 230 and 240 of the above-described structure enable adjustment of the light conduction direction, thereby facilitating more flexible arrangement of the first and second optical devices 210 and 220 within the apparatus housing 100.
It should be noted that, in the embodiment of the present application, both the first working surface 211 and the second working surface 221 may be light emitting surfaces, and light is finally emitted out of the device housing 100 through the light transmitting region 110 by light emission, so that the optical function is performed. Of course, the first working surface 211 and the second working surface 221 may be light receiving surfaces, and light passing through the light transmitting region 110 may be finally transmitted to the first working surface 211 and the second working surface 221 to exhibit an optical function.
The method can also be as follows: one of the first working surface 211 and the second working surface 221 is a light-emitting surface, and the other is a light-receiving surface. In a specific operation process, light emitted from the light emitting surface is finally transmitted to the outside of the device housing 100 through the light transmitting region 110 after being transmitted, and the light outside the device housing 100 is projected onto the light receiving surface after being transmitted through the light transmitting region 110.
In a further technical solution, the inner walls of the first light guiding section 231 and the second light guiding section 232 may be provided with light reflecting layers, so that a light diffusion phenomenon entering the first light guiding section 231 and the second light guiding section 232 may be reduced, thereby facilitating more light to be accurately transmitted. Specifically, the light reflecting layer may be a metal plating layer or a paint layer.
In the writing instrument disclosed in the embodiment of the present application, the writing instrument may further include a circuit substrate 300 attached to the first inner wall of the instrument case 100, and the first optical device 210 and the second optical device 220 are both disposed on the circuit substrate 300 and electrically connected to the circuit substrate 300. In this case, the circuit substrate 300 is disposed on the first inner wall, so that the space occupied by the housing inner cavity 120 can be reduced, and the arrangement of the circuit substrate 300 does not hinder the arrangement of the first optical device 210 and the second optical device 220 in the apparatus housing 100, and meanwhile, the circuit substrate 300 can supply power to the first optical device 210 and the second optical device 220, thereby being capable of helping to ensure the realization of the detection function of the first optical device 210 and the second optical device 220.
In the writing apparatus disclosed in the embodiment of the present application, one of the first optical device 210 and the second optical device 220 may be a light emitting device, and the other may be a light receiving device. In this case, the first optical device 210 and the second optical device 220 may cooperate with each other, thereby enabling the writing instrument to perform the functions of emitting and receiving light. Specifically, as shown in fig. 3, the first optical device 210 may be a light emitting device, and the second optical device 220 may be a light receiving device, so that the first optical device 210 emits a certain light, the light can irradiate on the surface of the object to be detected, and the light reflected by the object to be detected can be received and detected by the second optical device 220 serving as the light receiving device, thereby implementing the function of the optical module 200.
Alternatively, one of the first optical device 210 and the second optical device 220 is an infrared light receiver, and the other is an infrared light emitter, in which case the writing device has an infrared recognition function.
Of course, the first optical device 210 and the second optical device 220 may also be other kinds of optical devices, for example, one of the first optical device 210 and the second optical device 220 may be a camera, and the other may be a fill-in light. Of course, the first optical device 210 and the second optical device 220 may be both a camera or a fill-in light, and may also be other types of optical devices, and the embodiment of the present application does not limit the specific types of the first optical device 210 and the second optical device 220.

In a further technical solution, the light emitting device may be a color detection light emitting body, and the light receiving device may be a color detection sensor, and in a specific working process, the color detection light emitting body may emit light and irradiate on a surface of an object whose color needs to be detected, and since objects of different colors may reflect light of corresponding wavelength bands and absorb light of wavelength bands corresponding thereto, a spectral response curve of the light emitted by the color detection light emitting body may be changed. The color detection sensor is a sensor capable of realizing spectral detection, and the color of the detected object can be identified by detecting the spectral change of the light reflected by the detected object by the color detection luminous body. The color detection process and principle are well known and will not be described in detail herein.
In the writing device disclosed in the embodiment of the present application, the second working surface 221 may face the light-transmitting area 110, as shown in fig. 3 and 4, so that the light path connection between the second working surface 221 and the light-transmitting area 110 is more direct, and thus the light transmission between the external light and the optical module 200 is more accurate, which is beneficial to reducing the loss of light propagating in the medium.
In a further technical solution, the second working surface 221 may be attached to the light-transmitting area 110, specifically, no gap is formed between the second optical device 220 and the light-transmitting area 110, so that a gap can be prevented from being generated between the second working surface 221 and the light-transmitting area 110, and further, a foreign substance can be prevented from entering the gap to affect the normal operation of the second working surface 221. Meanwhile, the mode of realizing assembly through pasting is beneficial to the more compact structure of the writing device. Of course, this structure can make the second working surface 221 closer to the light-transmitting region 110, so as to shorten the light propagation path, further reduce the loss of light during the propagation process, and improve the accuracy of the writing device in detecting light.
